Thanks for the comments, it's still in the design stages as yet and has to be proven... I'm just hoping it has enough stopping force with the 1:1 ratio pedal and 3:1 booster only a good road test will tell.
The booster is a Lockheed ''type'' they were used on a lot of British cars in the 6o's and 70's and still used today. They are available in various boost ratios for different applications, the one I used is listed for lots of old heavier cars from Jaguar Mk 2's, Bristols and even ambulances.
I used copper brake pipe as that's what I had, it is rated to 2200 psi which I don't think this will ever achieve. Copper is commonly used in UK and I have been using it for around 30 years without any problems. The 5/16 reservoir tubing is Cunifer (copper/nickel alloy) again what I had around. If this proves to work I might also replace the 3/16 lines with Cunifer.
